the drawing is composed of a rectangle and a semicircle 18 cm 22 cm

Answers

What do you need?
The perimeter is L + w + L + perimeter of a semicircle.
L = 22 cm
W = 18 cm
Perimeter can be one of two answers. You need to specify where the semicircle is.  Formula for semicircle is
pi * r
r = 18/2 = 9 or
r = 22/2 = 11
So the perimeter of the semi circle is pi * 9 = 25.12 The total Perimeter = 22 + 22 + 18 + 25.12 = 87.12

It can also be 22 + 18 + 22 + 34.54 = 96.54 There are even more possiblities for perimeter. I would have the same problem if you asked about area.

Why not put more details in and I'l give you the correct answer. Here is what we need to know
1. Where is the circle on the 22 cm side or the 18 cm side?
2. What are you looking for: perimeter or area? As soon as you answer these I'll be back.

 

Susan received grades of 78, 93, 82, and 76 on four math exams. What is the lowest score she can receive on her next math exam and have an average of at least 85 on the five exams?

A) 96
B) 94
C) 92
D) 90
E) 88

Answers

Answers:
Choice A) 96

==========================================

Explanation:

The original list of scores is {78, 93, 82, 76}
Add x to the list to get this new list {78, 93, 82, 76, x}

Let's find the average of the new set
Add up the values and divide by 5. We force this average to be 85 since this is the grade Susan wants
(78+93+82+76+x)/5 = 85
(329+x)/5 = 85
329+x = 85*5
329+x = 425
x = 425-329
x = 96

So if Susan gets a 96 or greater on the fifth test, then she'll have an average of at least 85 (that score or greater)

∠YXZ and ∠ZXW are adjacent and supplementary angles. If m∠YXZ = 37°, what is m∠ZXW?

A. 143°
B. 37°
C. 53°
D. unknown

Answers

Answer: Choice A) 143 degrees

To get this answer quickly, you subtract the given angle (37) from 180 to get 180-37 = 143

The more longer answer would look something like this
x+37 = 180 .... the two supplementary angles add to 180 degrees
x+37-37 = 180-37 .... subtract 37 from both sides
x+0 = 143
x = 143
where x is the measure of angle ZXW

Native Americans once lived near Cartersville, Georgia, in an area that is now a state park. They constructed burial mounds that often contained artifacts, such as beads, feathers, and copper ear ornaments. One of the park's mounds is 63 feet in height. Be a Math Detective. If the top of the mound is rectangular in shape with a perimeter of 322 yards, what could be the side lengths of the rectangle?

Answers

Final answer:

The sides of the rectangle atop of the mound could be multiple pairs of measurements. One such possible example is 100 yards by 61 yards which satisfy the perimeter equation, given the perimeter of the rectangle is 322 yards.

Explanation:

The question is asking about the side lengths of the rectangular top of an ancient mound in Cartersville, Georgia. This is a math problem that uses the concept of perimeter.

The perimeter of a rectangle is given by the formula: P = 2l + 2w where P is the perimeter, l is the length, and w is the width. We know that the perimeter of the rectangle is 322 yards. We can solve for the sides (length and width) by setting up equations using various combinations of numbers that, when plugged into the formula, result in a sum of 322.

It's important to note that we won't have a unique solution to this because a rectangle's perimeter doesn't determine its side lengths uniquely, but only within certain limits. So, there could be multiple correct answers.

For example, if we consider the length to be 161 yards, and the width to be 0 yards, it would still satisfy the perimeter equation. But since width cannot be zero, we can suppose the length to be longer side and width to be smaller, say 100 yards and 61 yards, which also add up to produce a perimeter of 322 yards. So, one possible solution is 100 yards by 61 yards.

Step-by-step explanation:

(5.23x + 3.76) – (3.67x – 6.39)

(a + b) – (c – d) = a + b – c + d

Remove the parentheses and change the signs as needed:

What is the associative property

Answers

The associative property is the ability to group certain numbers together in addition/subtraction and multiplication problems because their operations are interchangable. 

Example 1: 

1 + 2 + 3

We can solve this by first doing 1 + 2 = 3, and then adding 3 + 3 = 6. OR we can start with 2 + 3 = 5, and add 5 + 1 = 6. We can even do, 3 + 1 = 4, then add 4 + 2 = 6. Either way, we end up with the same correct answer. 

Example 2:

1 x 2 x 3

Same thing applies to multiplication. We can start by doing 1 x 2 = 2, and then 2 x 3 = 6. OR we can do 2 x 3 = 6, then 6 x 1 = 6. Just like the one above, we can also do, 3 x 1 = 3, then 3 x 2 = 6. Either way you group them, you get the same answer. 

Example 3:

- 1 - 2 - 3

We can do - 1 - 2 = - 3, then - 3 - 3 = - 6. OR - 1 - 3 = - 4, then - 4 - 2 = - 6. OR - 2 - 3 = - 5, then - 5 - 1 = - 6. Again, same answer, three different ways to group it.

THIS DOES NOT WORK WHEN THE ADDITION/SUBTRACTION and MULTIPLICATION OPERATIONS ARE IN THE SAME PROBLEM

If given 1 + 3 - 7 x 4, you cannot rearrange the components like you can with the associative property. You will end up with drastically different answer when there is only one way to do this. 

Here is an incorrect example of it. 

1 + 3 + 7 x 4
1 + 10 x 4
11 x 4 
44.

That is wrong. The correct way is 

1 + 3 + 7 x 4
1 + 3 + 28

Now because all of the operations match you can use associative property to arrive at the same answer the three different ways. 

4 + 28 = 32. OR 1 + 31 = 32. OR 29 + 3 = 32. See the difference in the answers?

Lisa arranges six square paintings as shown in the area of the arrangement is 225 cm² what would it cost Lisa to frame her arrangement at a cost of $.12 per centimeter

Answers

Final answer:

To frame Lisa's arrangement of six square paintings, the total cost would be $43.20.

Explanation:

To find the cost of framing Lisa's arrangement, we need to calculate the perimeter of the arrangement and then multiply it by the cost per centimeter. Since the arrangement consists of six square paintings, we can calculate the side length of one square by taking the square root of the total area of 225 cm². The side length of one square is 15 cm, so the perimeter of one square is 4 multiplied by 15 cm, which is 60 cm. Since there are six squares, the total perimeter of the arrangement is 6 multiplied by 60 cm, which is 360 cm. Finally, we multiply the total perimeter by the cost per centimeter of $.12 to find the total cost of framing, which is 360 cm multiplied by $0.12, equaling $43.20.

What is the equation for the sum of three consecutive even numbers totaling 198.

Question 4 options:

n+n+2+n+4=198

3n=198

n+3=198

Answers

Let the first number be represented by x.  Then the next is x+2, the next x+4.  Add these 3 expressions together and equate the sum to 198.

Final answer:

Option B: n+n+2+n+4=198

The equation for the sum of three consecutive even numbers totaling 198 can be represented as

n + (n+2) + (n+4) = 198,

where n is the first even number.

Solving the equation, the first even number is 64, and the consecutive even numbers are 66 and 68.

Explanation:

The equation for the sum of three consecutive even numbers can be represented as n + (n+2) + (n+4) = 198, where 'n' is the first even number. Let's solve the equation:

Combine like terms: 3n + 6 = 198Subtract 6 from both sides: 3n = 192Divide both sides by 3: n = 64

So, the first even number is 64, and the consecutive even numbers are 66 and 68.

Have you ever experienced a time when you couldn't really describe something you saw in a way that others could understand? If so, you may understand why some experts think eyewitness testimony is unreliable as evidence in scientific inquiries and trials. New insights into human memory suggest human memories are really a mixture of many non-factual things. First, memory is vague. Imagine your room at home or a classroom you see every day. Most likely, you could describe the room very generally. You could name the color of the walls, the floors, the decorations. But the image you describe will never be as specific or detailed as if you were looking at the actual room. Memory tends to save a blurry image of what we have seen rather than specific details. So when a witness tries to identify someone, her brain may recall that the person was tall, but not be able to say how tall when faced with several tall people. There are lots of different kinds of "tall." Second, memory uses general knowledge to fill in gaps. Our brains reconstruct events and scenes when we remember something. To do this, our brains use other memories and other stories when there are gaps. For example, one day at a library you go to quite frequently, you witness an argument between a library patron and one of the librarians. Later, when telling a friend about the event, your brain may remember a familiar librarian behind the desk rather than the actual participant simply because it is recreating a familiar scene. In effect, your brain is combining memories to help you tell the story. Third, your memory changes over time. It also changes the more you retell the story. Documented cases have shown eyewitnesses adding detail to testimony that could not have been known at the time of the event. Research has also shown that the more a witness's account is told, the less accurate it is. You may have noticed this yourself. The next time you are retelling a story, notice what you add, or what your brain wants to add, to the account. You may also notice that you drop certain details from previous tellings of the story. With individual memories all jumbled up with each other, it is hard to believe we ever know anything to be true. Did you really break your mother's favorite vase when you were three? Was that really your father throwing rocks into the river with you when you were seven? The human brain may be quite remarkable indeed.
